WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 365.434, dated June 28, 1887.

Application filed March 5, 1887.

for doors; and its object is to provide a device which will be simple in construction and effi' cient in operation; and the novelty consistsin certain features of the construction, shown in the accompanying drawings, as will be hereignatcs the door, and B the door-frame.

inafter described and claimed.

In the drawings, Figure 1 is a perspective view of a door provided with my improvements, the door being opened so as to show the guide-plate or trip on thedoor-frame; and Fig. 2 is a perspective of the weather-strip and its casing detachedfrom the door. Fig. 3 is a detail view.

Referring to the drawings by letter, A dis T e door is hung upon the door-frame by means of hinges a, in the usual manner, and to the opposite side of the door-frame, upon its inner lace, I secure the guide-plate or trip b. trip b is set in a recess in the side of the frame, and consists of a metal plate having its lower edge, b, inclined downwardly from front to rear, and it is secured in place by screws passed through slots 0. An inclined groove, 0, is formed in the face of the d0orfran1e just below the trip, the upper edge of the groove coinciding with the lower edge of the trip.

D is an inclosing-case secured to the side of the door near its lower edge, as shown. The rear side of'this inclosing-case is hollowed out or cut away, so as to form the shoulder d, extending entirely across the same and at the end edges of the case. Extending from this shoulder d to the bottom of the case I secure the slotted plates E E. The weather-strip F is held between these slotted plates E E, and its outer end, or end nearest the swinging edge of the door, is provided with a pin, f, which projects through the slotted plate E and engages the lower inclined edge of the trip b 1n the operation of the device. The oppos1te end of the weather-strip is pivot-ally secured This Serial No. 229,833. (No model.)

to a plate, G, which is adjustably secured to the plate E by means of a screw, 0, passed through the slots in said plate into the plate G. The weather-strip is pivoted by means of a pin,f', secured in the end thereof and in- "plate E as provided with two slots, 6, through one of which the screw 6 is passed to secure the block G. In practice, a'single screw will be generally found sufficient to secure this block G; but it maysonietimes be found desirable to employ two screws, one passed through each slot, 1

In order to facilitate and cheapen the manufacture of my device, I form the plates Ewith two slots, 6, also, although only one is necessary.

H is a leaf-spring having one end perinanently or rigidly secured to the under side of the shoulder (1, its free end extending toward the swinging edge of the door, and I is alink connecting the free end of the spring with the upper side of the weather-strip.

In operation the block or plate G is adjusted to such a position that the inner end of the weather-strip will always rest against the floor or door-sill. The spring H will hold the outer end of the weather-strip off the fioor when the door is opened, and when the door is closed the spring will hold the pin f against the inclined lower edge of the trip I), so that the weather-strip will be forced positively downward and caused to bear against the floor or door -sill with certainty when the door is closed.

Thearrangement of devices just described, operating'as set forth, prevents the weatherstrip being broken when the door is opened,

Having thus described my invention, what to the inner face of the plate E, the weather- I 5 I claim, and desire to secure by Letters Patstrip supported by and between the block G cut, is and the plate E, and a spring having one end 1.
